In this case if fullurl started with http://www. then it is a match
Note that you CANNOT put quotes around it or it becomes a literal match which will not work as intended in the bash script example below.
if [[ $fullurl == http://www.* ]]; then
echo "do something"
Another example say we want to delete every file or dir in a path except sometihng that starts with "hellothere":
for file in `ls -1`; do
if [[ $file == hellothere* ]]; then
echo "oops electrum $file - do nothing"
rm -rf $file
We could also change the if above to match "hellothere" at the end or in the middle eg. $file== *hellothere*
